T0 to 1071/0712, it 11mg concern.-

Be it known that I, FRANK J OHNSON, a citizen of the United States of America, residing at Afton, in the county of Ohenango and State of New York, have invented certain new and. useful Improvements in Horse-Collar Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of ref erence marked thereon, which form a part of this specification.

This invention relates to a lock for fastening together and permitting the separation of the upper ends of the two sides of a horse collar, its object being to facilitate the placing and removal of the collar, and to provide there for a reliable and easily-"operated fastening device.

The invention consists in certain novel construct-ions and combinations of devices, which will be readily understood from the following description, with reference to the accompanying drawings, in which- Figure 1 is a perspective view of my improved collar-lock with the two parts connected or locked together. Fig. 2 is a similar view with the parts separated. Fig. 3 is a view of the lock provided with a modified form of latch.

Referring to Figs. 1 and 2, the letters A A indicate curved plates adapted to be secured to the upper ends of the two parts of a collar, respectively, the shanks an and a a being adapted to be secured on opposite sides of the longitudinal indentations of the collar, and provided with suitable rivet-hol es, 1), and slots 0 to receive rivets by which the plates may be se cured to the inner leather of the collar. The plates A A are respectively provided with flanges or face-plates B 13, adapted to stand across the end edges of the two parts of the collar. From the face-plate B of the plate A projects a bolt, D, provided with a transverse groove, E, and having its outer end beveled on its outer surface, as shown at d. In the face-plate B of the plate A is formed a slot, 0, adapted to receive the bolt D, which will project therein sufficiently to carry its groove E behind the face-plate B. To the rear side of this face-plate B is hinged a latch, F, provided with a notch, j, which coincides with the slot C. This latch F is pivoted to the rear side of the face-plate B at one end of the slot 0, and has its pivoted end provided with an extension, G, which forms a thumb-piece under which is arranged a spring, H, one end of which bears against the plate A and the other against the thumb-piece, so that thereby the latch will be held normally in its closed position, as shown in Fig. 1., at which time the intermediate portion of the latchengages with the groove E of the bolt and prevents the latter from being withdrawn. By pressing upon the thumb-piece G the latch will be raised out 'of engagement with the bolt, so that the latter may be withdrawn and the two parts of the lock separated.

The letter k designates a lug which projects from the plate A on the rear side of the latch and prevents said latch from being forced lat erally by the bolt D when the latter is inserted in the slot 0.

The operation of the lock will be'readily understood. \Vhen the bolt is inserted in the slot 0 the beveled face (I strikes and forces upward the latch, which falls into the groove E so soon as the face-plates come together, and holds them in that position. To

separate the two parts of a collar it is only necessary to press the thumb upon the thumbpiece G and withdrawt-he bolt from the slot C.

In the modificati on shown in Fi 3 the thumb; piece is dispensed with, and at its opposite end the latch is provided with an endwisc proj ection, I, by which it may be operated. A springlug, m, bears against the rear side of this latch and holds it in position by friction.

' By providing the plates A and A with the slots 0 a, through which rivets may pass, I am enabled readily to adjust the plates by simply remow'ing the rivets from their rear ends I), and the plate A having a face-plate, B,

7 provided with a slot to receive and a latch to engage said bolt, substantially as described.

2. The combination, with the plate A, having the face-plate B and transversely-grooved bolt D, of the plate A, having the face-plate B, provided with the slot Cto receive said bolt, and the spring-actuated latch F, pivoted be hind said face-plate l3 and arranged to engage said bolt, substantially as described.

3. The combination, With the plate A, having the slotted face-plate B, of the spring-latch F, pivoted behindsaid face-plate, and provided with the thumb-piece G, and the spring arranged under said thumb-piece, substantially as described, and for the purpose set forth.

4. The combination of the plate A, provided with the lug k and face-plate B and latch F, arranged to prevent said latch from being forced laterally rearward, substantially as described,

In a collar-lock, the plates A and A, provided with the rivet-slots 0 near their front ends, and the rivet-holes near their rear ends, substantially as described.

In testimony whereof I affix my signature in 2 5 presence of two witnesses.
